哈～不知道怎麼下標題，不過直接看圖和程式碼就能懂囉～
如果用post把資料傳到server上，參數是array或dictionary時，key和value要怎麼下呢？
這是在PostMan上下Key和Value。
iOS程式可以依樣畫葫蘆～自己創造key，value不變，全部塞到要POST出去的dictionary中。
for (int i = 0; i < [photoDetail count]; i++) {
key = [NSString stringWithFormat:@"photos_detail[%i][photo_name]",i];
value = photoDetail[i][@"photo_name"];
[parameters setValue:value forKey:key];
key = [NSString stringWithFormat:@"photos_detail[%i][photo_rate]",i];
value = photoDetail[i][@"photo_rate"];
[parameters setValue:value forKey:key];
key = [NSString stringWithFormat:@"photos_detail[%i][photo_start_x]",i];
value = photoDetail[i][@"photo_start_x"];
[parameters setValue:value forKey:key];
key = [NSString stringWithFormat:@"photos_detail[%i][photo_start_y]",i];
value = photoDetail[i][@"photo_start_y"];
[parameters setValue:value forKey:key];
}
[parameters setValue:typeOption[@"new_type"] forKey:@"type_option[new_type]"];
[parameters setValue:typeOption[@"start_year"] forKey:@"type_option[start_year]"];
[parameters setValue:typeOption[@"start_month"] forKey:@"type_option[start_month]"];
程式印出結果：
parameters:{
“photos_detail[1][photo_name]" = “3/3_FR2013-10-16_1.jpg";
“photos_detail[1][photo_rate]" = “";
“photos_detail[1][photo_start_x]" = “";
“photos_detail[1][photo_start_y]" = “";
“photos_detail[2][photo_name]" = “3/3_FR2013-10-16_2.jpg";
“photos_detail[2][photo_rate]" = “";
“photos_detail[2][photo_start_x]" = “";
“photos_detail[2][photo_start_y]" = “";
“photos_detail[3][photo_name]" = “3/3_FR2013-10-16_3.jpg";
“photos_detail[3][photo_rate]" = “";
“photos_detail[3][photo_start_x]" = “";
“photos_detail[3][photo_start_y]" = “";
…
“type_option[new_type]" = 1;
“type_option[start_month]" = 12;
“type_option[start_year]" = 2013;
}
如此POST送出到server就有效果囉～
參考：Is it possible to send an array with the Postman Chrome extension?。
